Hi all, Robert Scheitlin, GISP, Ken Buja I have web map with editable featureLayer. After click on my feature i get atrributes (using hitTest), and after click button "Query" query result displays as graphicsLayer and after another click graphic adds to graphicLayer. Idea of doing that is to merge several features in to one feature and update featreLayer after click on button. Now after click button "Update" i want to update graphicLayer features in my featureLayer, but it does not update. I paste full code to show how it is done: <!DOCTYPE html>

I lost Robert Scheitlin, GISP, Ken Buja, i changed - - - - "symbol: sketchViewModel.graphic.symbol"(JS version 4.9) to "symbol: sketchViewModel.crateGraphic.symbol" (JS version 4.14) and "view" to "view:view". now it does polygon sketch, but doesn't update featureLayer. It does not show any error in console, i do not understand <!DOCTYPE html>

Hi all, I am trying to create polygon feature, in JavaScript Version 4.9 it works, but when i change it in version 4.14 it does not work. I asked how to create polygon in another Question (Create Polygon Feature: Java Script ), it seems everything OK, but sketch created sketch doesn't updates in featureLeyer (can not "Apply edits"). Here is a code from JavaScript version 4.9 that works fine, how can i update it in version 4.14? Thanks. <!DOCTYPE html>

Hi again, I have changed code, Robert Scheitlin, GISP helped me. I still try to configure code, use code Robert gave me and code we have in template ArcGIS API for JavaScript Sandbox. Now i can click on template, draw polygon sketch, but it does not apply edits to Featurelayer and gives error. Se images and code: templates.on("select", function(evtTemplate) {
// Access the template item's attributes from the event's
// template prototype.
attributes = evtTemplate.template.prototype.attributes;
unselectFeature();
document.getElementById("viewDiv").style.cursor = "crosshair";
// With the selected template item, listen for the view's click event and create feature
const handler = view.on("click", function(event) {
// remove click event handler once user clicks on the view
// to create a new feature
handler.remove();
event.stopPropagation();
featureForm.feature = null;
var sketchVM = new SketchViewModel({
view,
layer: graphicsLayer,
pointSymbol,
polylineSymbol,
polygonSymbol
});
// Call create method to create a polygon with Click.
sketchVM.create("polygon", {mode: "click"});
// Create a new feature using one of the selected
// template items.
editFeature = new Graphic({
geometry: event.geometry,
symbol: sketchVM.graphic.symbol,
attributes: {
IncidentType: attributes.IncidentType
}
});
// Setup the applyEdits parameter with adds.
const edits = {
addFeatures: [editFeature]
};
applyEditsToIncidents(edits);
document.getElementById("viewDiv").style.cursor = "auto";
});
});
// Call FeatureLayer.applyEdits() with specified params.
function applyEditsToIncidents(params) {
// unselectFeature();
featureLayer
.applyEdits(params)
.then(function(editsResult) {
// Get the objectId of the newly added feature.
// Call selectFeature function to highlight the new feature.
if (
editsResult.addFeatureResults.length > 0 ||
editsResult.updateFeatureResults.length > 0
) {
unselectFeature();
let objectId;
if (editsResult.addFeatureResults.length > 0) {
objectId = editsResult.addFeatureResults[0].objectId;
} else {
featureForm.feature = null;
objectId = editsResult.updateFeatureResults[0].objectId;
}
selectFeature(objectId);
if (addFeatureDiv.style.display === "block") {
toggleEditingDivs("none", "block");
}
}
// show FeatureTemplates if user deleted a feature
else if (editsResult.deleteFeatureResults.length > 0) {
toggleEditingDivs("block", "none");
}
})
.catch(function(error) {
console.log("===============================================");
console.error(
"[ applyEdits ] FAILURE: ",
error.code,
error.name,
error.message
);
console.log("error = ", error);
});

Dear Robert, I changed you code using 4.14 version of create sketch polygon, now i can draw polygon click on template in form, but can't update in featureLayer, it seems everything ok, but does not work: const templates = new FeatureTemplates({
container: "addTemplatesDiv",
layers: [featureLayer]
});
// Listen for when a template item is selected
templates.on("select", function(evtTemplate) {
var sketchVM = new SketchViewModel({
view,
layer: graphicsLayer,
layer: graphicsLayer,
pointSymbol,
polylineSymbol,
polygonSymbol
});
// Call create method to create a polygon with Click.
sketchVM.create("polygon", {mode: "click"});
sketchVM.on("create-complete", addGraphic);
function addGraphic(event) {
// Create a new graphic and set its geometry to
// `create-complete` event geometry.
const graphic = new Graphic({
geometry: event.geometry,
symbol: sketchVM.graphic.symbol,
attributes: attributes
});
graphicsLayer.add(graphic);
const edits = {
addFeatures: [graphic]
};
applyEdits(edits);
console.log(graphic);
}
function applyEdits(params) {
featureLayer.applyEdits(params).then(function(editsResult) {
// Get the objectId of the newly added feature.
// Call selectFeature function to highlight the new feature.
if (editsResult.addFeatureResults.length > 0) {
const objectId = editsResult.addFeatureResults[0].objectId;
}
})
.catch(function(error) {
console.log("===============================================");
console.error("[ applyEdits ] FAILURE: ", error.code, error.name,
error.message);
console.log("error = ", error);
});
}
});

Hi guys, I am trying to use ArcGIS API for JavaScript Sandbox this sample to add polygon feature, i also use codes taking from here https://community.esri.com/thread/224031-how-to-create-a-polygon-js-api-49?commentID=811443&et=watches.email.thread#comment-811443 from Robert Scheitlin, GISP, but can not combine this two sample to add polygon and update attributes. Thank you for your help Here is a code samples i use (you can see them in links too): // ***********************************************************
// Call FeatureLayer.applyEdits() with specified params.
// ***********************************************************
function applyEdits(params) {
featureLayer.applyEdits(params).then(function(editsResult) {
// Get the objectId of the newly added feature.
// Call selectFeature function to highlight the new feature.
if (editsResult.addFeatureResults.length > 0) {
const objectId = editsResult.addFeatureResults[0].objectId;
//selectFeature(objectId);
}
}) // called when sketchViewModel's create-complete event is fired.
function addGraphic(event) {
// Create a new graphic and set its geometry to
// `create-complete` event geometry.
const graphic = new Graphic({
geometry: event.geometry,

Hi guys, Need your help. I have code, Anne Fitz helped me. I make selection (highlight) of features on click and clear highlights when click on "Clear highlights" button. Now i want to unselect selected feature when click on Right mouse button, so others have to stay selected. I make some changes, but it became funny map, it does job vice versa, i cant select (highlight) when click on left button of mouse, but i can select when click Right one. You can see on my uploaded code.
